What is helical ribbon impeller?

Helical ribbon impellers are designed especially axial movement of the liquid (in the process of ‘replacement of liquids’). Such an impeller can be designed with an additional inner helix used to pumping in the opposite direction. This is needed for the mixing of high viscosity materials.

What is anchor impeller?

Anchor impellers are used specially for highly viscous flow, with the viscosity ranging from 10 to 100 Pa. s, which is typical of polymer reactions and some processes in food industries. The reactions are normally carried out under laminar flow. Anchor impellers are also suited for pseudoplastic and thixotropic fluids.

What is hydrofoil impeller?

The hydrofoil is a 3 bladed high efficiency impeller. It is known for its high efficiency because it is able to produce the greatest amount of flow per horsepower in the spectrum of Mixer Direct’s line of mixing blades.

Which impeller is good for low viscous liquid?

In many cases, a hydrofoil impeller blade is well-suited for lower viscosities, while an axial flow or turbine pitched blade is better for mixing highly viscous substances. Furthermore, density of a substance is an important characteristic related to viscosity.

What is an anchor agitator?

Anchor-type agitators are principally designed to mix highly viscous products and non-Newtonian fluids, i.e., they lack a certain degree of viscosity because it depends on the temperature. These agitators can be mounted in tanks with rounded or conical bottoms.

What is propeller agitator?

The propeller agitators or stirrers are those of axial flow working at high speed and are used for low viscous liquids. The flow streams, starting from the agitator, move through the liquid until they are deflected by the bottom or walls of the tank.

What are the types of impeller?

The impeller of a centrifugal pump can be of three basic types:

• Open impeller. Open impellers have the vanes free on both sides.
• Semi-open impeller. The vanes are free on one side and enclosed on the other.
• Closed impeller. The vanes are located between the two discs, all in a single casting.

How do I choose an impeller?

The size of vessel used for mixing will determine the diameter of the impeller. A general rule of thumb for axial or radial flow patterns is the diameter of the impeller be ⅓ of the vessel’s diameter, so a 10 cm beaker would require approximately 3 cm impeller.

What is difference between impeller and turbine?

An impeller or impellor is a rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid.

How many types of agitators are there?

There are two types of Agitators commonly used, 1. Mechanical Agitators, 2. Electronically Controlled Agitators, I’ll demonstrate commonly used Mechanical Agitators.

What is pitch blade turbine?

The Pitch Blade Turbine impeller is one of the most widely used impellers and one of the oldest designs of the mixing industry. While useful in most applications, this design excels in aggressive mixing requiring high power input per volume as well as flow.

How do I choose an agitator?

Selection Criteria of Industrial Agitators The viscosity of the bulk. Exact function required (blending, dissolving, dispersion, heat exchange, chemical reaction, crystallization, emulsification, suspension, etc). The mixing cycle (batch size, the time required for agitation, material addition sequence, etc)

What kind of impeller is a helical ribbon?

Which is the best description of a SLD impeller?

SLD impeller (double helical ribbon screw impeller) is a kind of low speed impeller, Outline of type SLD is close to the inwall of tank and type SLD has a large mixing diameter, result in the increase of liquid circulation inside the tank. It has applications in processes of heat transfer of high viscosity medium..…… more

Which is the most economical laminar flow impeller?

The anchor impeller is the most economical laminar flow impeller. It is most effective in squatty batches where vertical pumping is not as important as in tall batches. It is low speed impellers which used in processes of mixing and heat transfer of middle, high viscosity medium.…… more
